Internet data communications AdLib OCR Evaluation Preliminary Data Sheet July 2002 Lithium Niobate Polarization Controller Waveplate Configuration The following figure shows a device cross section and a possible orientation of the five waveplates with respect to a: V1 V2 X Ma, a5 a, a4 ~ja, cX2 2,14, a, a, a3 Figure 1 . Waveplate Configuration 1-1255(F)a To get a quarter waveplate oriented at a, the voltages applied to the device are as follows : V1 = Vdc(90) + Vdc(0) + Vac(0) " cos(2(x) + Vac(90) " sin(2(x) V2 = Vdc(90) - Vdc(0) + Vac(0) " cos(2(x) - Vac(90) " sin(2(x) where Vdc(0), Vdc(90), Vac(0), and Vac(90) are the four characteristic voltages of each waveplate. Absolute Maximum Ratings Stresses in excess of the absolute maximum ratings can cause permanent damage to the device . These are absolute stress ratings only. Functional operation of the device is not implied at these or any other conditions in excess of those given in the operational sections of the data sheet. Exposure to absolute maximum ratings for extended periods can adversely affect device reliability.
